Just like any other variable, we complete the same process

Now we can test it, let's say k=4, d=6, and c=2, let's find the value of g

OR
Since the first line passes thru the origin, you can read off its slope from the coordinates of the other point (3,2): the slope is m = 2/3.
A line perpendicular to the first has slope -3/2, the negative reciprocal of 2/3.
Thus, the perpendicular line is y = (-3/2)x + b. Subbing 0 for y and 0 for x, we get b = 0. Therefore, the equation of this new line is y = (-3/2)x.
Answer:
in one minute they rake
leaves working together.
Step-by-step explanation:
If Maya rakes the leaves in x minutes, then, in one minute she rakes
leaves.
In the case of Carla, if she rakes the leaves in y minutes, in one minute she rakes
leaves.
Therefore, to know the portion of leaves they can rake in one minute working together, we need to sum up both of the portions each one of them rake in one minute, this gives us: 
Now, to simplify this expression:

Thus, in one minute they rake
leaves.
Answer:
2000 meters
Step-by-step explanation:
Length of rectangular park = 400 m
Width of rectangular park = 200m
Around the park means perimeter so ,
perimeter of rectangular park = 2(length+width)
perimeter of rectangular park=2(400+600)
=2(1000)
perimeter of rectangular park=2000m
